Abstract

Researchers of the Paul Scherrer Institute (PSI) have made detailed 3-D images of a commercially available computer chip. This marks the first time a non-destructive method has visualised the paths of a chip's internal wiring (just 45 nanometres— 45 millionths of a millimetre — wide) and its 34-nanometrehigh transistors clearly without distortions or deformations. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications
